Product details

Overview

IRFU9014PBF from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in IPAK (TO-251) through-hole package, rated for -60 V V_DS, 0.50 Ω R_DS(on) at V_GS = -10 V, and -5.1 A continuous drain current at T_C = 25 °C. It features repetitive avalanche rating, fast switching (t_r = 63 ns), and dynamic dV/dt capability (-4.5 V/ns), enabling use in DC-DC converters and motor control circuits.

For engineers reviewing the IRFU9014PBF datasheet, IRFU9014PBF pinout, IRFU9014PBF application, or IRFU9014PBF equivalent, this device serves as a rugged, low-R_DS(on) P-channel switch for industrial power supplies, load switching, and high-side configurations where logic-level gate drive compatibility and PCB-mount thermal performance are critical.

Technical Context

The IRFU9014PBF employs third-generation trench MOSFET technology optimized for low conduction loss and robust avalanche energy handling (E_AS = 140 mJ). Its gate threshold voltage range of -2.0 V to -4.0 V supports both standard and logic-level gate drivers, while its body diode exhibits t_rr = 80–160 ns and Q_rr = 0.096–0.19 μC for controlled commutation in synchronous rectification.

Thermal design is enabled by R_thJC = 5.0 °C/W (junction-to-case) and R_thJA = 50 °C/W (PCB mount), with maximum power dissipation of 2.5 W on a 1" FR-4 board. The device's internal source and drain inductances (L_S = 7.5 nH, L_D = 4.5 nH) are characterized for accurate switching waveform modeling.

Pinout & Package

IRFU9014PBF uses the IPAK (TO-251) through-hole package with three terminals: Drain (D), Gate (G), and Source (S). The case outline conforms to JEDEC TO-251AA, featuring a single straight lead configuration optimized for wave soldering and mechanical stability in industrial PCBs.

FAQ

What is the maximum continuous drain current for IRFU9014PBF at 100 °C case temperature?

The IRFU9014PBF supports -3.2 A continuous drain current at T_C = 100 °C, per its Absolute Maximum Ratings table. This derating reflects thermal limitations of the IPAK package and must be validated with actual PCB layout and ambient conditions. Designers should consult Fig. 9 (Maximum Drain Current vs. Case Temperature) in the Vishay datasheet S26-0614 for precise thermal boundary mapping before finalizing heatsinking.

Does IRFU9014PBF have a specified avalanche energy rating?

Yes, IRFU9014PBF is repetitively avalanche rated with E_AS = 140 mJ (single-pulse) and E_AR = 2.5 mJ (repetitive), tested under defined conditions (V_DD = -25 V, L = 6.3 mH, R_g = 25 Ω). These values confirm suitability for inductive load switching without external clamping, provided pulse width and duty cycle remain within limits shown in Fig. 11 and Fig. 12 of the datasheet.

What is the gate-source threshold voltage range for IRFU9014PBF?

The gate-source threshold voltage (V_GS(th)) for IRFU9014PBF is specified from -2.0 V to -4.0 V at V_DS = V_GS and I_D = -250 μA. This range enables compatibility with both standard -10 V gate drivers and logic-level controllers operating down to -3.3 V, making IRFU9014PBF suitable for direct interfacing with microcontrollers in low-voltage industrial systems.

Can IRFU9014PBF be used in surface-mount applications?

No, IRFU9014PBF is specifically the straight-lead (through-hole) version in IPAK (TO-251) package. For surface-mount use, the DPAK (TO-252) variant IRFR9014PbF-BE3 is recommended. Mixing packages risks solder joint reliability and thermal performance-IRFU9014PBF requires wave or hand-soldering into plated-through holes per Vishay's mounting guidelines in document 71197.

What is the typical body diode reverse recovery time of IRFU9014PBF?

The body diode reverse recovery time (t_rr) of IRFU9014PBF is 80–160 ns under test conditions of T_J = 25 °C, I_F = -6.7 A, and dI/dt = 100 A/μs. This parameter is critical for synchronous rectification and freewheeling paths; designers must account for associated Q_rr (0.096–0.19 μC) in efficiency calculations and EMI filtering.
